Part 1

Only a few hundred feet left of the hike, and yet it was the most brutal. The remaining trees on the mountain vanished as we made the final ascent to the top. I watched my friend Kyle sprint the final few steps up the barren, dirt trail, disappearing from view. “

Wait up!” I yelled, quickening my pace to catch up. I heard whooping and hollering as I stumbled up the final few steps.

“Ah, what a view!” exclaimed Kyle, stretching his arms high into the sky. Before I could even look around, I put my hands on my knees, feeling my leg muscles cramping up.

“Dude, that was one of the most exhausting hikes we’ve ever been on.” I took a deep breath. “But it was so worth it.”

“Tim, you gotta look at this view, man!” shouted Kyle.

I leaned up, looking at my burly friend with a sly smile. We were both pretty well built. I was 6-foot-1, 205 pounds and have competed in a few bodybuilding competitions at this point. I have a nice build which compliments my gym shorts and tank top nicely. Kyle, on the other hand, had me beat. Filling his gym shorts and t-shirt was a 6-foot-3, 220-pound stud. We’ve been gym buddies for years, and we’ve put quite a bit of size on together. We met in high school and bonded together through thick and thin as we navigated the life of being openly gay teenagers. We were roommates in college, and now we share an apartment together as we both try to start our lives. While we’ve never officially been together through the years, we were about as comfortable as could be with each other. Best friends.

“Hey. Hey,” chirped Kyle, snapping his fingers at me. “Earth to Tim, come back to me.”

I snapped out of it, realizing I was staring at his muscular body. “Sorry, you wanted me to look at the view,” I joked, punching his shoulder.

I stepped up onto the ledge, feeling the wind gust up the mountainside. “Woah.” That was all that could be said. Our clothes whipped around as the gust seemed to only pick up, throwing dirt and small debris up at us. After a few miles’ hike, we were seemingly a few thousand feet above the ground. You could practically see the slight curve of the Earth from up here! Open grass-lands with sparse trees surrounded us, a city visible off in the distance.

“Hey, let’s get a photo to celebrate this!” I said, pulling my phone out of my pocket. We flipped around, folding our arms around each other as we took an epic photo. I stared at it for a moment happily. We both looked happy.

“Aw dude, that turned out so good,” Kyle said admittedly.

*CRACK* A loud noise split the air as we jumped, unsure of what the sound was. My head shot up to the location of the noise—the sky. I gasped. “What the—!”

I was interrupted by Kyle. “—Fuck?” he finished.

We both watched in awe as a massive meteorite painted the sky. But most pieces weren’t crossing from left to right like your typical meteorite. They were getting... larger? Our expressions turned from awe into horror as we realized it at the same time. The meteors were breaking up and coming right for us. A massive chunk the size of a building crashed at the base of the mountain, sending us tumbling backwards as the Earth shook and more chunks started to land around us.

Run!” screamed Kyle. We bobbed and weaved our way around the descending trail as debris rained all around us, looking for cover. I kept pace with Kyle as we slid into a large crevice in the rock on the side of the mountain. All we could do was wait the remaining 30 seconds as massive fragments rained across the mountain. A massive chunk the size of a suitcase landed in front of us, only feet away from our legs. A weird hissing noise released from it as it cracked open, almost as if the pressure inside was pouring out.

We sat in silence as the sounds that filled the sky came to an abrupt halt. “Is it… over?” I questioned, not expecting an answer. The temporary space hail-storm had calmed down. I got up to my feet and turned around, extending a hand in Kyle’s direction. “Come on, let’s get out of here.”

With that, we fled down the mountain as fast as we could. I would bet that no one has ever walked back on this trail so fast before. Miniature craters were everywhere scattered across the region, tiny rocks filling each individual space. Each released a similar hissing noise as we continued down the trail. Not 15 minutes later, we made it. And what sat at the bottom was the most impressive thing I had ever seen in my entire life.

“Holy shit!” I yelled, jogging up to it. In front of me was a massive crater with a ginormous meteorite towering out of it. It must have been over 5 stories tall, still smoldering from its recent journey to the ground. I could feel Kyle uneasily walking behind me as I stopped in my tracks. This was the closest I could get without the heat becoming too unbearable. A lava-like substance melted off of it, pooling onto the ground.

“I think we should go…” I could hear Kyle’s voice trail off behind me.

He was right. We had no idea if there will be more. “Okay, one moment,” I agreed. I reached into my pocket once again, grabbing out my phone and snapping a photo of the massive rock. When I was putting away my phone, I noticed it. A bulge pushed out against the front of my gym shorts. I was so caught up in the moment I hadn’t even realized. I was a pretty average size, coming in at 6 inches, so the bulge was definitely noticeable. Wanting to ease Kyle’s nerves, I turned around, laughing. “Hey Kyle, look! I’m rock hard.” I watched as his eyes rolled as he turned around to walk back to the car, smiling.

I adjusted myself as I followed Kyle, ready to call it a day. If I had only stayed another minute, I would have noticed something. The rocks were slowly crumbling apart, being eaten by our Earth’s atmosphere as an invisible chemical was released into the air. It was odorless, tasteless, and impossible to see. This gas would only hover in the atmosphere for a few minutes before dissipating entirely. Unfortunately for Kyle and I, we were exposed to something far beyond our understanding. A virus that was not from Earth. And it had already started working its magic.

Our car roared down the road as Kyle drove us back towards the city. News trucks and police cars whizzed past the opposing side of the street towards the crash site. Nothing would be left by the time they arrived. Just the craters. Any trace of the virus remained with us. I scrolled my phone past tons of ‘Breaking News’ articles. “Gigantic Meteorite impacts Eastern Coast. Largest in over a century.” They were endless. Videos were popping up all across Twitter, Instagram, and Youtube as people filmed their own experience of this crazy astrological event. I felt my cock chubbing up again as I watched the videos. Man, I was pretty horny. I saw Kyle move out of the corner of my eye as I noticed him adjusting his rock hard bulge as well. He’d always been huge, coming in at 7 inches. But wow, his bulge looked fantastic.

I shook my head and looked away, trying to occupy myself with other thoughts. Something crazy just happened, that should be the last thing I should be thinking about. I looked out the side mirror as the mountain slowly drifted away. Kyle stayed quiet with his eyes peeled to the road as we trekked closer to the city. I felt my eyes drifting, before—

“Hey.” I felt my shoulder being shaken as the car slowed to a stop. “We’re at your house.”

How long had it been? I looked at the clock. 1:58 p.m. blinked in response. Not even an hour ago we were running away for our lives, and now we were just expected to carry on like it was a normal day at home. We walked into my house, flopping onto the couch in exhaustion. Not only was today incredibly terrifying, we had also completed one of the most grueling hikes in the entire area.

I flipped on the TV to see what had developed as Kyle sat next to me on the couch. “We’re getting reports that the massive meteorite that crashed into the Earth at 1:03 p.m. have actually disappeared! The massive crater remains, but no trace has been left behind by the ominous large-scale event that occurred earlier today. We’ll keep you updated as we learn more.”

I turned down the volume as they started rambling about unrelated topics. “Disappeared?” I repeated.

“I don’t know, maybe they aren’t looking in the right spot?” responded Kyle.

“No, no that doesn’t make sense. They were showing photos at the base of the mountain.” We both sat in deep thought for a moment.

I felt my cock push against something wet, which brought my attention downwards again. I was throbbing hard down there again! I sighed exaggeratedly, adjusting it again. “I gotta go take care of this, I’ll be right back,” I said, annoyed.

I walked into the bathroom, closing the door. I leaned over the countertop. My arms looked pretty great, like they had been pumped at the gym. Which made sense—we had just been on a massive hike, and a lot of arm movement was involved. I looked down at my bulge, tracing the outline with my fingers. A soft moan left my lips as I savored the feeling. I felt it jump in response as I became more excited. “Alrighty, time to take care of you,” I said to myself.

I dipped my hand down into my gym shorts as my hand grazed my shaft. Man, it even felt big today. I must be really chubbed up. I dropped my shorts to my ankles as I looked in the mirror. My toned thighs complimented my form nicely, and I had a pretty good set of cock and balls to match. I felt my cock lurch again as I started stroking it sensually. I don’t know if I’ve ever been this hard in my entire life!

I slowly moved my hips around as I got into a rhythm. “Thaaat’s it,” I croaked to myself. With each stroke I could feel myself getting harder and harder, pre beginning to steadily leak out of me. My left hand grazed my muscular body as my other hand teased my cock, working my pole like I was trying to clean it. I could feel the sensation beginning to rise from my balls as I picked up the pace. My other hand fondled my balls as I got closer and closer to release. Fuck, I feel so huge, I thought. It was so hard that I don’t even think I could get it to go down if I wanted to!

I felt my balls contract as I hit the motherload. I watched in lustful awe at what was unfolding. Rope after rope of cum shot out of me, splattering against the mirror in front of me. And I felt a sensation I had never felt before in my entire life. My entire body felt flushed with heat for a few moments as I stared at myself in the mirror, my dick slowing down. I’d never cum that hard before, ever!

I looked down at my cock in my hand as it remained rock hard. Oddly enough, it felt… bigger? It looked bigger, at least. I pulled out a ruler from my drawer and placed it flat against my rod. My eyes widened as I noticed the impossible. The ruler read 7 inches. Seven? I knew for a fact that I was only 6 inches last month. Was I just that hard? I looked at the ruler, and then my cock again as the thought of being a bit bigger turned me on. I felt my cock throb again, it jumping slightly as I was just about to remove the ruler. I gasped as I saw a miracle perform. Displaying on the ruler in front of me, it showed I was just a hair above 7” now. This was cause for celebration! What guy didn’t like a little extra growth?

I cleaned up and slipped my underwear and shorts back up, my cock still hard against the front of my shorts. I walked out to the living room where the TV and Kyle were located. “Okay, you’re not going to believe this, but—” I stopped in my tracks. Laying on the couch in front of me was Kyle, his shorts completely down as he stroked his engorged meat.

“Oh hey. Sorry, I couldn’t help myself and you were in the bathroom. I’ll just be a minute. I won’t make a mess, I promise.” I felt my cock jump again in response, and I swear I could feel it growing just a little bit thicker. While Kyle and I had never officially been in a relationship, we had an ‘on and off’ friends with benefits situation for years. But this…this was beyond anything I had ever seen during those few years. Not only did his muscles look pumped, but his cock looked to be nearly 8 inches long.

“I—did you grow too?” I questioned.

“Grow? What do you mean?” he asked in response.

“I know for a fact you are 7 inches. That—” I pointed at his cock, “is not 7 inches.”

I walked back to the bathroom, feeling my cock bounce around my shorts as I got the ruler out again. I didn’t notice it before, but it actually felt a bit bigger moving around in there. “Okay, got it,” I exclaimed, sitting down next to him. His hands slowly slid up and down his thick, meaty shaft as I put the ruler right next to it.

I put the ruler flat against his solid meat, measuring the length of Kyle’s endowment. My mouth dropped. “Dude… you’re 8.25 inches long.”

He gasped. “Bull. Shit.” He grabbed the ruler, placing it against himself as he checked to confirm. “What..?” We sat there confused for a moment. This was all turning me on way too much.

“All right stud, I don’t know what happened, but let’s take care of this.” My tanktop was already removed before I finished the sentence. I stripped my shorts and underwear off, my cock leaking as I approached you. God, he looked fucking amazing. I got off only 5 minutes ago, and yet I was incredibly aroused again by the sight before me. I rubbed my hands across his body-builder-like pecs and traced it down towards his 6-pack.

“Fuckk dude. That feels so good,” he groaned. His pleasure was only working me up even more. I leaned in, slowly kissing his lips as my hands squeezed his biceps. I was in absolute heaven. I grinded my cock onto Kyle’s, feeling both of our endowments getting even harder than I thought possible. He placed his hand on my shaft, caressing it up and down as we made out. When I thought I possibly couldn’t take any more, I felt a shudder roll through my entire body. And then the weirdest thing happened. I felt my cock engorging, like it was getting harder over and over again. I could feel Kyle’s fingers spread slightly as it seemingly got more erect. The shudder filled each of my muscles, my frame slightly expanding from all the added pleasure. I didn’t realize I was starting a cycle that could result in growth. Massive growth.

Kyle opened his eyes and then did a double take. “Tim...”

I continued feeling his muscles as I was lost in the moment. “Tim...”

I opened my eyes, slightly annoyed at having to stop. “What?” I asked, disappointed.

“Are you sitting up right now?” he asked.

“Sitting up, no why would I be—” My voice caught in my throat.

“Hold on, stand up.” We both scrambled to our feet as we looked each other in the eyes. I couldn’t believe it. For the first time in my entire life, I was taller than Kyle? But how would that be possible? “Are we growing..?” I asked nobody in particular.

I clasped the ruler on the couch, bringing it back over to us. I placed it against my dick as my jaw dropped. Displaying on the edges of the ruler was 8 inches of cock. Turned on by this, my cock throbbed. I watched it grow another millimeter. No, 2 millimeters. I dropped the ruler in surprise as my eyes shot back to Kyle. It wasn’t just me growing. We both were. I could already tell that his muscles were slightly bigger. I thought they were just pumped earlier, but I could see now that they were larger than they used to be. Not by much, but they were larger. “You’re growing too.”

Kyle looked at me with a look of lust and confusion. “This doesn’t make any sense.” He responded.

“Hang on a moment!” I ran back towards the bathroom, bringing out a scale, placing it in front of us. “Okay, you first!” I beckoned to him.

I watched Kyle step on the scale as the numbers started rising below him. We looked at each other. The scale read 240 pounds. “How much did you weigh when you checked after the gym yesterday?” I asked.

“I swear it was no more than 220 pounds.” he responded, shocked.

“Okay, let’s do me.” I brushed him off to the side as I stepped onto it, holding my breath. My jaw dropped even further as I watched it rise to 245 pounds. “Holy shit. I was 205 pounds this morning.”

I looked over at Kyle. Knowing how much weight I had put on, I suddenly noticed everything about my body. My arms looked big. A decent mound showed up before, but now it looked like an entire tennis ball was under my biceps. My chest and abs had more definition than before, too. I could never quite achieve a 6 pack, but one was definitely visible now. And my cock… I swear it was already a bit larger than before. It was achingly hard, reaching all the way up to my belly button, if not slightly past it. I must have gained 20 pounds since we got home. “What is happening to us..?” I asked.

I looked down at the scale again. 246 pounds. I stared for a bit as I tried to make sense of it all. 247 pounds. I gasped, stepping off the scale. I heard him moan as I looked over. His cock leaked a few drops of pre onto the floor. He was already looking just a smidge larger than before.

“Kyle… We didn’t just grow. We are actively growing,” I said, completely speechless.

“Just..gotta..get off, real quick,” he responded. I watched as he jerked his rod of a cock.

A thought flickered across my mind. “Hang on, step on the scale real quick, and then continue.” I guided him over to it, watching his feet step up. 244 pounds. Already 4 pounds added in mere minutes. I watched with wild curiosity as he stroked himself, wild with lust as he started getting closer to getting off. 245 pounds. I could already feel my cock dripping as I watched him enjoy the pleasure. 247 pounds. His pace quickened as his breathing got shallower. 249 pounds. This was it. I watched his hips buck back and forth as large shots of cum shot out, hitting the ceiling with excessive force. And not just a little bit either. A lot. I couldn’t believe just how much liquid was really emptying from his swelling balls. My eyes flicked down to the scale. 255 pounds. I watched as his load started to empty and he looked down at the scale. 258 pounds. 14 pounds in less than two minutes.

“What the fuck…” he whispered. The scale visibly slowed down in how much weight was being added as soon as he came.

“Okay. We need to figure this out.” I paced around the room, sliding my clothes back on. My package was snugger than ever before, making a sizable bulge on the front of my shorts. The waistband of them slightly pulled against my body, a bit too tight. Speaking of tight, my tank top straps formed around my shoulders nicely as my chest was slightly visible through the arm holes. We were now both the same size, rivaling both height and weight. In just a little over 1 hour, we had put on a crazy amount of our body mass.

I started the conversation. “Okay listen. Clearly we’re both growing because of something that happened today at the mountain. I don’t know what, but something happened.” Kyle nodded in agreement. I could see his pecs prominently displayed in his shirt as he slid it back on. We weren’t quite professional bodybuilder status, but we were starting to look like gym rats. “From what just happened on the scale, we know that the more horny and sensitive we get, the faster we grow.” I looked back at him to confirm he understood my statement.

“All right, I’m still following,” he said.

I continued talking. “We need to figure out what’s happening before we grow too large. Clearly we’re getting hornier, and the growth is accelerating, too.” I looked down at my bulge. It already looked slightly more stretched out than a minute before. Or was it just my imagination? I couldn’t tell.

“Clearly this is related to the meteorite incident earlier today. I say we start there.” I pointed at the TV.

“But nothing’s left. They already said that,” Kyle answered anxiously.

“We need to try at least,” I said. I stepped back on the scale. 270 pounds. “And we need to hurry,” I added.

 

Part 2

The car roared down the road on its way back the same way we had come from just earlier that day.

“Just focus on the road,” I advised Kyle. I was even having a little bit of trouble. Feeling the extra bulk on my arms, chest, legs, and package as I sat in the passenger seat was certainly hard to ignore. Especially with the light vibrations of the road shooting up through our bodies. I looked down at myself again. God. We must have each put on another 20 pounds since we left the house. I gave a quick flex, watching my biceps bunch up to the size of baseballs now. I placed my hands on my lap, my larger bulge lolling around in my shorts, looking like I was stuffing a salami down there.

“You were saying?” Kyle replied in an exaggerated tone as he glanced at me. He’s right. If we want to truly figure out what is going on, we need to keep our heads on straight before it’s too late. I put my hands at my side, trying to force it out of my head as our car neared our destination.

The car stopped. Must have dozed off again, I thought as I opened the car door. The fresh mountain air rushed in to meet me as I took it in the familiar environment. I stretched, feeling my tank top tightly rise up my body to the bottom of my 6-pack abs, reminding me that I had already put on 100 pounds in just a few hours. Even when putting my arms back down to my sides, the bottom of my stomach was visible.

My eyes shot over to Kyle. I felt my cock jump in my pants as I watched him get out of the car, his muscles rubbing against the edges of the door as he strained more than he needed to in the past. I closed my eyes tight, turning my head away as I felt my cock slowly slide against the fabric. Was that me growing? Getting hard? I don’t know. What I do know is, it is getting easier to lose control. Scattered rays of sunlight floated through the air, combing perfectly with the fog that lightly rolled across the environment. We walked back to where it all happened just earlier that day. I could feel my dick chubbing up at the thought of being back in this place. Something about it called to me. I could definitely tell that my bulge was starting to become pretty noticeable. And heavy.

“People have definitely been here since we were,” Kyle chimed in. He is right. Tire tracks lined the road. This made sense, however. It seems we arrived after all the buzz from the news trucks and first responders.

Not even two minutes after we left the car, I saw it. A massive crater. But just as the news had stated, nothing was there. Just the crater.

“Well, I guess we should take a closer look,” I suggested. Kyle and I leaned over the edge, climbing into the crater. It was pretty deep. It was easily more than triple the height of our heads and wider than an entire building. My hands felt a bit of a zap as I descended down the ledge, using the slanted walls of the crater to reach the bottom.

“Here, let me help you,” I told Kyle as I helped lower him down. I placed a hand underneath his thicker, juicy thighs as I felt the corded muscles shift around with exertion. Just the sheer thought of his muscles contorting and bursting out of his clothes made me horny beyond belief. I could feel the straps of my tank top heavily pushing against my shoulders as I helped him all the way down.

“Tim, careful buddy…” I snapped out of it.

“What?” I questioned back defensively.

“You were staring. And, well, you’re harder than a rock.” I looked down, gasping. He was right. My cock was fully hard, and definitely larger than it had ever been so far. It pushed straight out from me, nearly an entire foot, making an impossibly large tent in front of me. I gasped, adjusting it so it was supported by my waistband, sticking straight up. Even so, it sat higher than my belly button, coming up to the first row of abs. Since my tanktop didn’t even cover my waistband at this point, you could see an inch or two of my thickening shaft before the hem of my shirt covered my throbbing cockhead.

“Fuckk,” Kyle said erotically as he looked at my morphing form. “Let’s just keep moving.”

We walked down the dirt crater until we reached the bottom. The further down I walked, the harder I could feel myself getting. Every inch of my body wanted me to get even closer to the center. I could tell it was having an effect on Kyle too. Even he was erect beyond belief at this point. I could see the sleeves of his shirt straining against his bulging biceps. I knelt down, running my hand along the ground, looking for signs. But there was none. It just felt like..dirt. Not even a small trace of the meteorites remained. But..I did feel like I had to be here. A calling. To those who were present when the meteors fell that absorbed the wonderful chemical. I felt a certain energy radiating off the dirt as I dug my hands through it. I moaned, feeling my cock shoot a small load of pre against my deepening abs. Kyle looked down at me inquisitively, watching as I ran my hands through the dirt, almost as if I were trying to gather it.

“Actually… are we sure it’s such a good idea to be back here?” asked Kyle. I stood up, taking in the energy as I rolled my neck, feeling it coursing through my body. I groaned again as I felt my shirt grow tighter. I could feel his eyes staring at my thickening rod as it slid up towards the top of my abs.

“I think we should leave…” Kyle said worriedly, as I started feeling my body. My thoughts feel cloudy. I’ve never been this horny in my entire life. I closed my eyes, relishing the feeling as I felt his hand tug on mine, his voice muddled and distant as I leaned into the feeling. Kyle watched in lust-filled horror as he could physically see my muscles expand. Slowly, but still expanding all the same. My tank top grew tighter against my ballooning frame, the straps growing closer to their limit with each moment. The bottom of my shirt barely even covered my abs anymore, but held tightly enough to my body, that the only part of it that wasn’t touching me was the fabric that strapped around my swelling cock. But even so, behind my thick, veiny shaft, my 6-pack abs started to transform into an 8-pack.

The sides of my pecs were visible through the arm holes before, but now they were nearly exiting them entirely as they grew thicker and beefier with each passing moment, now larger than a dictionary each! I could also feel my shirt stretching along my back, the fabric increasingly stretching thinner as it started to struggle to contain me. My hands drifted up and down my body as I slowly rocked my hips back and forth. My shorts were getting pretty tight now as well. My balls had expanded so much that it looked like entire grapefruits were stuffed down there. The weight of them alone slightly pulled my shorts down, revealing more and more of my groin. My ass bulged out, a beyond-perfect bubble butt appearing as my thighs stretched the leg holes of my shorts to the limit. I had quickly gone from ripped to shredded. Easily rivaling the size of professional bodybuilders, with an endowment that was impossibly larger.

Even in Kyle’s rational mind, it was hard not to gain pleasure from such an awe-inducing visual. Just imagine watching your gay best friend balloon in front of you, slowly becoming the man of your dreams as he only wants more and more size. Even he could barely refrain from touching his own growing body as he felt his pleasure build up even more. His cock was practically slowly unraveling within the confines of his shorts as his own build grew even beefier. I slid my cock out from the cloth prison of my shirt it was confined to, wrapping my hands around its slick shaft. It was throbbing so hard I could hear my heartbeat in my ears as I watched it swell even larger.

I could feel my fingers slowly being forced apart as it thickened larger than my abs. I rubbed its swelling length up and down as my moans grew deeper as my vocal chords expanded. At this rate, I was beyond even the largest bodybuilder on Earth. I had to be over 400 pounds of pure, rippling muscle with one of the largest cocks on the planet to match. I felt the yanks on my arm grow stronger as a growing Kyle tried to pull me away, his body expanding at a rapid rate now as well. His shorts became so bloated that tiny tears were starting to form across his legs. Between his cock, balls, thighs, and ass, the bulge was so extreme that it looked like an air hose had been pumped into a sealed space. But all the excessive force he was using trying to pull me away was having an effect. The exertion on his upper body was coinciding with his lust, growing him faster. His shirt filled out to the max as his feet dug into the ground, yanking me with all his might. All his feet did was activate the dormant chemicals that lied within our bloodstreams, only quickening the pace at which we grew.

I continued stroking myself, my cares melting away as I became obsessed with my growing body. I never wanted to stop. I liked the feeling of my clothes stretching so tight they started to tear. I liked the feeling of my cock rising up into my pec valley, as my pecs pushed out to the size of king sized pillows. And I loved the feeling of my head growing further away from the ground as my height only increased. My shoes started to split as my socks strained to contain my elongating feet. My biceps passed the size of bowling balls! I could feel the ridges of my traps growing up at an angle towards my head, only stretching my shirt further. It was at this point I felt the largest yank of them pull against my bulging arms. It threw me off balance, snapping me out of the temporary trance I was in.

Tim!” Kyle yelled. I saw his face flood with relief as he realized I was back with him. I shook my head, clearing it as I took full notice of my size. I was massive. I must be over 500 pounds and 7 ½ feet tall! And Kyle..he must’ve been 450 pounds and 7 feet tall. Small tears lined my entire outfit as I heard them slowly spreading. My eyes then followed his body down, widening as I saw his obscene bulge tearing through his shorts everywhere as well.

Tim! We need to go!” Kyle screamed.

“Y-you’re right,” I replied. I noticed that my voice was considerably deeper, easily rivaling a bass in choir. We started walking forward, my rigid shaft now so large I could bend my head down and lick it if I wanted to. I can’t, I thought. I need…to keep myself…under control. I felt its weight bobbing in front of me as pre leaked off of it like a fountain, puddling around my feet as I walked. The sheer weight of my balls kept pulling my shorts down, making it nearly impossible to contain them. I swear I could physically hear my cum factories sloshing, producing more as a quickening rate. I stretched my shirt as tight as it would go, placing my impossibly erect cock underneath it. My hope was that it would help me keep my hands off of it. It stayed pinned against my body, jumping with anticipation with each step. It looked like I stuffed a telephone pole between my shirt and my body. It was just a tad above my pec valley now, beginning to slowly get closer to being level with my nipples. Pre practically dumped off of it, instantly soaking through my shirt and flowing down my rippling frame.

We made it to the upper edge of the crater, our lumbering forms having difficulty getting over the lip as our muscles rubbed against each other in a way no human has ever experienced. As we swiftly walked to the car, I could feel disappointment forming in the back of my mind that I couldn’t stay longer. That I couldn’t have the most mind-bending orgasm. That I couldn’t keep growing, and bury myself in the dirt as the electrifying feeling spread more and more. I forced the thought out of my head. If we wanted to stop this before we became too large, we were starting to run out of time.

We made it to the car, nearly an entire foot larger in size than when we had left, but with a bunch more mass. Getting into the car wasn’t just difficult, it was nearly impossible. I pushed the seat back as far as I could, leaning it back as well. Even so, it was quite the effort! If I was driving, it would have been impossible with how thick I had become. Fortunately, Kyle was a bit smaller than me, so he was still able to fit. For now. The seats creaked as we both squeezed into the car, the tires’ suspension audibly groaning with the added weight. The steering wheel was nearly smothered by Kyle’s pecs as his bulge hung nearly down to his knees, flooding off the front of his seat. His hair brushed the ceiling as his thick arms rested on the steering wheel.

I watched as the rest of glorious biceps burst through the sleeves. I felt my cock jump, pinned against my pecs. I could feel more tears forming across the clothes on my body. We are still growing. Even sitting, I had to lean my head forward to be able to fit in the car.

“What do we do now?” I asked Kyle. He looked up at me, thinking methodically.

“I think we need to go to a doctor. Maybe they could figure out what’s going on. Or at least find someone who does. Clearly going to the site of the place that grew us was a bad idea. It’s time we reach out for help.” It was the best lead we had. I nodded, as the car kicked into drive and we sped off down the road once again.

 

Part 3

The car only felt more crammed with each moment that passed. We were already 30 minutes down the road at this point. The early signs of evening painted the sky as the sun started to crest behind the mountains. At this rate, our muscles were both already far larger than any humans’ could possibly get on the planet. Beyond professional level. Beyond steroids. Beyond surgery. With the shredded tank top wrapping around my body, it just felt even more ridiculous. How long would it be until we couldn’t move? How long would it be until it was impossible to hide? Will the growth ever stop? The constant vibrations of the road sent jolts up my body as I bit my lip. Must… maintain…control, I thought to myself.

“Only five minutes to the doctor’s office,” Kyle remarked reassuringly. “It’s in the middle of town, but it was the closest one. I called them and let them know what they’d be looking at ahead of time.”

A few minutes later, our car parked. It felt crammed. Beyond crammed. My head was hunched down now, the roof practically forcing me to stare at my pecs from how hard it shoved into my back. I struggled to open the door, my biceps grinding against the tight space as I flicked the handle towards me. Relief flooded through my entire body as the door opened. Getting out still proved to be a difficult task, however. My cock was nearly at the top of my pecs by now, thick enough that it was nearly as wide as my waist, as large and round as a barrel. My back was so massive that I knew I would never be able to sit in a car again at this rate. Would I even be able to fit through bus doors in an hour? I doubted it.

My corded thighs made contact with the ground as the car creaked and rose as my weight lifted out of it. The same went for Kyle, who was close behind me in every way. The last remnants of my socks snapped off as my weight sank onto the asphalt. The industrial city smell swam through the air as my eyes landed on the door across the street. ‘Emergency Care.’ I shrugged my shoulders at Kyle, hearing my shirt audibly tear as my back felt a new slice of air pushing against it. This was the best option we had. And probably the last.

We lumbered across the street together. The buildings rose high around us, spiking into the sky. The clinic itself was small, just one story tall, but wide enough that it could treat many patients at a time. I could feel the stares. I watched as a couple crossed to the opposite side of the street to avoid us. I glanced down again, not even able to see my feet because of how much mass was in front of me. I mean, we looked absolutely ridiculous. My tank top had more skin showing now than cloth! My beyond-skin-tight gym shorts were pushed so far down by my bloated balls that the poor fabric practically sat on my thighs. My leaking, titanic cock was comically encased by the remains of my tank top, but even then, the thick bulbous head of it was starting to rise out of the neckhole! Not to mention all of my clothes were soaked by the pure amount of pre that had run down my body.

Kyle was looking at himself as well. His cock wasn’t hard right now, but his clothes were in the same predicament as mine. In fact, his cock was so coiled up in his shorts that I could physically see the skin of his shaft tearing through multiple parts of them. Our thighs rubbed together as we walked in the doors of the lobby. I even had to slightly duck through the door frame. Dead silence filled the air as we crammed our way in, two behemoths just walking together. I’m sure we didn’t even look real. Whispers fired out around us.

“How are they so fucking huge?”

“Is it even safe to have such a massive dick?”

“Gross. They look like they’ll be immobile soon.”

Each comment chubbed me up more and more as I felt my shirt tear further. One of the spaghetti-thin straps of my tank top snapped, folding off of me diagonally, leaving half of my massive torso exposed as my cock became fully visible to those surrounding us. A thick, throbbing rod just constantly pouring pre down my shelf-like pecs and deliciously deep abs.

“We’ll take you back here, sir,” a doctor beckoned urgently. I snapped out of it, Kyle looking at me with lust in his eyes. Even his clothes were dangerously close to becoming a thought of the past.

The door closed behind us as the doctor leaned against the counter. We were in your every-day, standard appointment room. One operating bed laid across the middle of the room, which I leaned against. A loud groan emanated from it as the metal frame took my weight.

“I got your call. I don’t know what’s happening, but if what you’re saying is true—” He paused, glancing at our heaving, hulking bodies for confirmation. “-—then we need to work fast. If the growth really is linked to your level of horniness, then I need to take some semen samples back for testing.”

I watched as he adjusted his bulge. I guessed he was enjoying the show. He wasn’t just seem excited, he seemed eager. Passionate.

“Here, take this. It’ll help keep your testosterone production lower.” He handed us each a small pill and a water bottle. An excuse to slow down our growth? Kyle and I both took it without hesitation.

“Now I need to obtain some samples,” he stated, as he got out a large cotton swab. “May I?” he asked. I nodded my head in agreement. The doctor took the swab and dragged it up the length of my wet, leaking cock. I shuddered with joy as my hips bucked, a small shot of pre spraying against the ceiling. I felt my voice catch in my throat as an electrifying feeling filled me up, my size lurching forward an entire inch in only a second.

“Fascinating.” he responded back. “Very…fascinating.” His hands traced my shaft just a moment too long, before he pulled it away. He walked over to Kyle, giving him the same treatment as he dropped the tests into a tube.

“Give me about 45 minutes to uh…run some tests, and I’ll be back.” I took a deep breath, meditating to keep my libido at bay. But as time passed, it only grew more difficult. I could see a sheen of sweat forming across Kyle’s head, too. It was getting very difficult to abstain from pleasure. The pill hadn’t done anything to help ease our orgasmic tendencies. Everything felt tighter as well. My shorts looked like a thong at this rate, with balls so large that they filled every inch of remaining space. They poured both out of the top of my shorts and the leg holes with size now. The door opened as the doc walked back in.

“Did you figure it out? What’s the issue?” I immediately asked. I saw as he slowly walked in that he an evil smirk spreading across his face.

“Issue? Oh. No issue. None at all. How are you boys feeling right about now?” he asked in a slow, seductive tone. Kyle cocked an eyebrow at me, before turning to him.

“What are you talking about?” he demanded.

“You don’t feel any better, do you? In fact, you probably are feeling really extra fucking horny, am I correct? Much more than when you arrived?” The room stayed silent as we both looked at each other’s bodies.

“Perhaps I may have ‘accidentally’ mixed up which pill I gave you. Wouldn’t it be a shame if I gave you an accelerated version of Viagra instead? I don’t even think they manufacture a product stronger than the one I gave you two.”

My eyes went wide with realization. We didn’t take a pill that lowered our testosterone production. We took one that did the exact opposite. As if to answer the silence, Kyle’s shorts completely snapped. His obscene bulge spilled off his body, as his balls slapped his shins. *GLORP. They quickly surged with size, now down to his ankles as a moan pierced the lust-filled air. His cock grew harder by the second, rising up his sweaty body as he started to give in. In fact, I could feel it too. I wasn’t just horny. I was unhinged! I was becoming so erect that my cock was nearly purple, standing up so straight that it now was at my collarbone. Plink. I felt my other tank-top strap snap away as my shirt tore off my body.

I moaned this time. Not just a discreet noise. A long, low moan as I felt my balls drop further. My thighs breached the absolute limit of my shorts as they finished their journey, ripping off entirely. They withered to the floor as my own balls dropped to my ankles, an audible sloshing ringing through the room as another shot of pre launched from my cockhead with so much force that it made an audible splat against the ceiling.

“Ohhhh. Tim. What’s…happening?” Kyle groaned as his own package swelled larger. The doc watched in eager anticipation as every last inch of fabric melted off of us both as we lost control.

“You can’t—” I started.

“Oh, but I can,” he interrupted in return. He slithered his hands up both of our sensitive shafts as we went rigid with pleasure. “Yes…that’s it. Grow…” He turned Kyle and me towards each other, getting out of the way and stepping back once again.

My eyes locked with Kyle’s eyes. Man, he looks so fucking sexy. Such monstrous muscles. I could physically see him growing. Swelling. I shouldn’t, but I…need….to—I felt a bump hit my chin. Distracted, I looked down with pure lust as I saw my one-eyed monster staring back at me. It was just about as wide as my torso at this point. It beckoned to me. How could I turn down such an amazing offer? I barely reached my head down, feeling my traps rise around my neck as I licked the tip. I practically vibrated with pleasure from the shock. Fuck it.

I placed my mouth around it, groping up and down my shaft as I felt my muscles rubbing into each other. I started pumping it like there was no tomorrow. And I was still getting hornier. I could hear Kyle’s moans flooding the room. I knew he was having just as much fun as I was. I hugged my expanding rod as I felt the first wave of cum launch through me. Load after load exploded into my mouth. I made sure to swallow every last drop of the savory liquid. Not only was it super-hot, but it felt incredible. In fact, I could feel more size piling onto me with each swallow of my thick, warm seed.

The doc took another step back. I knew he had an amazing spectacle filling his vision. With each volley of cum that shot down my throat, more size packed onto me. Whatever virus was embedded deep within me, kept reactivating over and over again as I fed myself. Audible creaks could be heard through the room as I started to dwarf the bed even more, leaning against it for support. I could feel my manhood shoving further into my mouth as it only grew larger. With how quickly my balls were expanding, the torrent of cum only got stronger. But it seemed with each delicious drop that traveled into my stomach, the more mass I put on. I could feel my mouth stretch wider to accommodate its fattening width.

My hips continued to buck uncontrollably, practically shoving it deeper and deeper into my throat. My arms that were stretching around it pushed in retaliation as they, too, inflated. In fact, there wasn’t a muscle on me at this point that wasn’t inhumanly large. I felt my neck crane to the absolute max, trying to fit as much of my swelling endowment as I could, but alas, it started to grow too large. I leaned my head back, cum gushing out of my mouth as my fat cockhead popped out, spraying over my head as it slowed down to a constant trickle of drooling pleasure.

A moment of post-nut-clarity hit me as I realized something. I felt pressure against my head. I looked up, watching as the roof was only an inch above me. Holy shit. I must be 11 feet tall. I brought my head down, my eyes settling back on my package. It was the most beautiful thing I had ever seen. My cockhead itself was larger than my entire head, and it sat at my eye level. Just the realization of this nearly made me lose control again. But what pulled me in even deeper was what was behind it. I heard grunting from the corner of the room. The doctor was gone at this point. The room wasn’t big enough for anyone but us, but he had served his purpose. Turning us into the men we were meant to be. Perhaps the visual of us both being molded into studs was just too much serotonin for his simple brain.

But Kyle…fuck. He looked incredible. Not quite as tall as me, but nearly equal in muscle mass. Every spare appendage he could use was worshiping his 5 foot long cock, arching high enough that it was above his head. He was leaning so hard against the wall that it was indented with his bulging shape as his low, booming grunts filled my ears.

Instantly I felt my own growth come back with a vengeance as the corruption completely overtook me. I waddled forward, my cock pushing forward another inch as I collided against him. Our dicks were sandwiched between our bookshelf-sized pecs, nearly blocking our mouths as we incessantly made out. Each of our poles bent to the side of each other’s heads as our hands rubbed up and down every available ridge of muscle covering us. I could feel my hair flattening under the ceiling. He pushed so heavily back against me that we both toppled backwards, flattening the bed underneath us as our muscles had begun to inflate even faster. Anyone left in the waiting room at this point could only hear our grunts, moans, and vibrations as they reverberated through the walls. And with each pound being added to our billowing forms, our voices only grew deeper and louder.

“Oh fuck, Tim. You’re becoming so huge!” Kyle yelled as he groped my ballooning pecs. I snatched his cock, watching it spray cum with enough force to shatter the window as I felt his weight increasing on top of me.

“Grow for me, Tim. Let me make you into a behemoth of a man.” A long moan exploded from my mouth as his words bounced around my brain. I felt my arms crash into the walls as the room only shrank around us.

“We’re going to become the biggest. Nothing can stop us. More. More. Moreee!” I yelled as I sank into the feeling that I once dreaded so much. I felt resistance on my chest as your own back smashed into the ceiling, our feet breaking through both the doors and the wall as they surged into the hallway. Between Kyle and me, nearly no space was left in the room. The fluorescent lights shattered, the room growing dark as the city lights shined through the broken window.

Seeing the deep, shadowy definition of Kyle’s muscles above me was beyond erotic. Each muscle was so large that the light couldn’t even wrap fully around them. Bump. I felt my own head crack into the walls as I realized that there was only one way out of here. I shoved my body into his, grinding our obscene muscles together as debris rained all around us. The pleasure that was generating between our cocks, pecs, balls, and legs rubbing together was insurmountable. I felt the wall crumble as the fresh outside air rushed in to make contact with our naked bodies. My arms broke through the walls as I felt my legs hit the other end of the hallway. We must have been as wide as two appointment rooms now, and nearly as long as the entire building.

I shimmied my way backwards, dragging my new mate on my ginormous muscles as more and more of the ambience of the outside world rose in my ears. Upon completely sliding out, I slowly got to my feet, helping Kyle up as well, as I felt my muscles surge out even more. In the last 30 seconds I had grown so much that I rivaled the entire size of the doctor’s office now. I was more than double its height as well, making me nearly 25 feet tall. I looked down, my pecs quickly bumping my chin. Looking down was barely even an option anymore. It was useless, anyways. My chest filled nearly all of my vision of anything beneath it, so thick and juicy that each pec rivaled the size of minivans. What part of my vision wasn’t taken up by my pecs, was most definitely taken up by my swelling telephone poll. It throbbed with anticipation, a steady waterfall of fresh pre pouring down it as it sat just above my head. I saw a few people running away as I turned back to my partner. I widened my stance as I felt my titanic thighs preventing me from walking. My cum swelled further until they touched the ground, and I felt the cool Earth become smothered underneath them. I tried to bring my hands together to touch my abs, but my biceps, triceps, and forearms had thickened so much they could only smoosh into my pecs when I tried to perform that action. Even if I couldn’t feel my abs, if Kyle was any indicator, I must have a sizzling 12-pack at this point.

I could feel my traps rise up underneath my ears, nearly creating a pillow for my head as I looked at him. He was frantically licking his cockhead, trying to coax any pleasure possible out of himself, but I knew just what to do.

“Turn around, big boy,” I commanded.

“Fuck me, Tim. Please. Fuck me!” he begged as I turned him around. Each step cracked through the asphalt as my cock grinded against his bulging, house-sized back. Pre slithered down each crevice, running like a funnel between his massive bubble butt. It was practically begging me to mate with him. I took a step back, my thick cock sliding down each ridge of his back as I felt his chest heave up and down with each breath. I continued stepping back until it sat level with his hole.

“Are you ready to grow fucking massive, Tim?” Kyle teased me, waiting for me to fill him with endless pleasure.

“I’ve never been more ready,” I responded, slowly pushing my cockhead between his archaic cheeks. In and in I pushed, already feeling my muscles convulsing with power as I felt Kyle’s hole grip my shaft tightly. I could hear crowds running out of buildings as the swelling only increased. In fact, I could literally see Kyle’s muscles writhing around, almost as if an unseen power was underneath, pumping them up. I pushed in as far as I could, multiple feet of pure cock pushing into his ass as I wrapped what parts of my hands that I could around his abs. My pecs were so godly, and his back was so padded that I could only reach my fingers just beyond his obliques before our muscles collided. But it was more than enough.

I began moving my hips back and forth, feeling Kyle’s body shift with lust as I started to sensually caress his muscles. The feeling was so amazing that I could physically feel each part of me ballooning with size. Anyone left on the ground could actually hear each body part stretching out, elongating, and deepening while our low moans rumbled through the streets, rattling the windows. I looked up temporarily, noticing that I was nearly 5 stories tall. All of the rooms that looked back at me were completely empty. Everyone had evacuated. Perfect.

I thrust into him again, my cock pushing all the way in as I gasped with pure orgasmic delight. I yelled with ecstasy as I thrust into him again, and again, and again, a sensation filling my entire being that I had never felt before. I felt it start in my balls, which were now so plump and heavy that they pooled around my feet. It rose up through my feet, which were larger than city buses, and into my thighs, which were so thick that I couldn’t spread my legs any wider. And of course, up into my cock. The more the feeling spread through my package, the faster I could feel it grow. I felt the walls of Kyle’s stomach press against me as it surged forward an entire foot, thickening so much that it instantly sent him into a cumming frenzy. Crying with pleasure as his own cock shot load after load, both above, and ahead of us, painting the windows of the buildings as we both swelled.

Seeing my beautiful partner enjoying himself so much was the final straw. I roared, windows shattering as I plunged my cock into you for the final time. I could physically feel my balls lift off the ground, smashing back into the asphalt as it exploded with force up through my monolithic shaft. My hips went wild, gyrating back and forth like an animal as I felt muscle nuke onto my frame. I could feel my hands get wrenched back from his stomach, not even able to reach his sides anymore as my pecs practically exploded forward, shoving into him. I felt my chest rise up into my jaw as my shoulders slammed into the buildings on each side, caving them in. My traps joined the party, rising up next to my ears, threatening to deafen me forever. My biceps puffed out so densely that I would never be able to reach my head again, enormous enough that a grain silo couldn’t even compare. My abs caved in so deeply, that a rock climber could use them as handholds. My ass bubbled out so thick that it could rival the size of the doctor’s office alone. It seemed with each heartbeat, I was putting on hundreds of pounds of pure muscle. Alongside each heartbeat, my monster cock continued shooting torrents of cum inside of Kyle, only making him into more of a mutant. Cum poured into the streets, nearly a foot deep as it clogged all the storm drains around us.

I began pulling out, my dick thickening so much that I knew you wouldn’t be able to handle it any longer. A long, guttural noise left my mouth as I felt it slowly slide out, still beyond rock hard. The buildings on both sides of my shoulders toppled, crumbling into the streets below. At this point we were both so lost in pleasure, that we didn’t even care anymore. The only way to stop the growth was to stop the pleasure, but when the pleasure is incapable of ending, what happens next? Besides, everyone had time to evacuate. I sighed with orgasmic relief as my colossal shaft exited him with an audible pop. It instantly shot up, wetly colliding with my absurdly large pecs as it rose multiple feet above my head.

Looking up at it, I noticed something even more odd. Nothing was above it. I looked down as much as my pecs would allow me. Even still, they filled my entire horizon below eye-level. My mouth opened with awe as I realized something. I was as tall as the tallest building. Multiple feet in front of me I could see Kyle realize the same. He was slightly shorter than me, but rivaled me in almost every way. A hot, leaking, muscle god. The thought of our titanic bodies growing larger than anything comparable filled me with the deepest form of lust and desire that I had ever felt. Then I noticed something off in the distance. Far, far away. Mountains. Not just mountains, however, but the craters that kicked this entire thing off in the first place.

“Kyle,” my heavy voice boomed, shattering windows in a mile radius. “Crater.” I lifted my arm up as much as I could, pointing off into the distance as Kyle’s face filled with realization.

“Crater,” he replied back to me. We were both so lost in lust that even the prospect of wasting energy on taking the time to talk was trivial. We still had full mental capacity, but we shared the desire for growth more than ever. That was the number one priority. We both started walking. Each footstep sent ripples across the entire city, debris falling off of buildings as craters were left behind us as wide as city blocks. Both of our balls were incapable of doing anything but drag themselves behind us at this point, furthering the destruction as cars flattened. Our swelling continued even as we walked. It seemed that no matter how much we both came, the growth was incapable of even slowing down anymore. Everything was sensitive. Even my muscles. Just the thought of my hand brushing my leg was enough to send volleys of cum thousands of feet into the air. But we trekked on, our eyes landing on the valley that was growing much closer.

Only a few minutes later, we arrived. It was much easier when you towered nearly double the height of an entire city, but admittedly with the pure size of our muscles, movement was beginning to grow limited. Our arms couldn’t even rest at our sides anymore, our lats, biceps, pecs, and forearms so densely packed that it was physically impossible. I brought my foot down, seeing the craters from the meteor-event earlier that day. At this point the main crater was barely even larger than my entire foot.

“Now!” Kyle commanded, and I knew exactly what he meant. At the same time, we both stepped onto the crater. If our earlier visit was any indication, this ground was corrupted with a deep chemical that did one thing: GROW. Perhaps it was because we had leaned into the feeling of the growth this time, or perhaps it was because of the surface area of our feet, but this time the effects of the chemicals hit us both instantly. A warm sensation that flooded from our toes to our heads in less than a second. It hit so powerfully that it was impossible to react in time. A noise I had never heard before escaped my throat as we both instantly started cumming rivers and valleys of thick, hot seed that shot into the lower stratosphere. I turned, shoving my monolithic shaft into Kyle’s as we frotted against each other, our hips gyrating so wildly that the cracks of our bones could be heard across the county as our bones adapted and shaped to fit their new entity. I thought nuked was a good explanation for how our growth in the city exploded through us, but this was beyond that. Way beyond that.

I felt as my feet quickly dwarfed the entire crater, smashing through the mountain that we had gruesomely hiked just earlier that day. The peak of it only reached my knees now, each leg wider than the entire mountain itself. But only within a few seconds, it was down to my ankle. Mass piled onto the both of us at a catastrophic rate as we swelled so quickly that we were each more than a mile wide. Our behemoth cocks stretched so absurdly high into the sky that pilots could see them without even looking down. And if they continued to watch the skyline, only a minute behind it would be our enormous, hulking bodies. I could feel my balls ballooning so large that they were rising up past my ass, each ball alone larger than an entire city. Sitting so plump on the ground that it rose behind us. In fact, the city that once towered above us hardly scraped our calves as we continued to rise up and up. The clouds passed our two-mile wide pecs as I rested my head on them with complete and utter gratification. At this rate, they were so large that I was unable to even see Kyle anymore. But I could certainly feel him. His monumental mass rubbed against mine as our cocks continued sliding and swelling around each other, towering more than double the height above our heads. My chin was permanently forced into an upward angle as my traps pushed against the back of my head. They were also so unrealistically boulderous that my hearing was muffled. The only sound that filled my ears was the absurd stretching of my muscles, the gallons of cum that landed on top of them, and my moans as they traversed from my godly form.

But somehow, even still, my sensitivity grew. A feat that didn’t even seem possible. Drool dripped off my lips as my eyes practically rolled back. My arms’ movement became severely limited as each one became thick enough to rival an entire state. Between Kyle and I’s bodies, we rivaled the size of the entire country! Anyone looking up would only see up to our thighs before they hit the clouds. Far above that, our thighs were so widely muscled with crevices so deep that entire cities could rest on each one. An immobile deity of muscles just surging beyond anything ever thought possible. Only one thought crossed my mind.

More. Moreee. Moreeeeeeeeeee!” I screamed as sonic booms burst off of my muscles, clapping across the sky as I felt my cock become… weightless? I was hardly aware of the destruction that had occurred underneath me as I felt that odd sensation travel throughout my body, from the top down. I watched as the night sky grew even darker as stars became extremely visible. Country-sized globs of cum circled the atmosphere as only endless amounts more launched out of us. I wasn’t quite sure what Kyle looked like at this rate, but I could tell just how tall he was. I felt his pecs pushing along each side of my obliques, so round and lovely that it was a perfect mount for his own colossal rod, which was still grinding against mine, but so large that it bent at an angle back towards the Earth.

I felt my body lifting up my thighs into the atmosphere, my country sized boyfriend lifting up with me. It was great timing, to be honest. My thighs had become so crowded alongside my balls that I wasn’t able to stand any longer, each so positively enormous that I was forced to spread them out as far as I humanly could. The fact that we could breathe in space barely crossed my mind. Must be a fortunate side effect of this necessary virus. I felt my body turning around due to the sheer force of cum geysering from my eye-ogling cock. My eyes settled on the Earth, the world shrinking in comparison to us at a rapid rate as I saw a massive crater covering nearly half the Earth. Fuckkk. Each pec must be the size of the United States now. No, bigger. No, much bigger. How fast were we swelling? It was nearly impossible to tell, but within only a minute, it seemed that the Earth had shrunken to smaller than the size of one of my balls, the gargantuan nut becoming so large and swollen that it nearly wrapped the Earth.

That was when my body turned just enough to settle on him. Kyle. Floating freely in front of me. His head was so tiny that I could barely see it on top of his excessively cramped muscles. In fact, he was practically just a wall of moving human flesh. It was actually quite impressive how fast I could see each curve and ridge becoming even deeper. I felt my body rumble deep from within with so much power that my skull shook, practically buried in pure muscle at this point. I clenched my eyes as tight as I possibly could as I felt the wave hit me once and for all.

Boom. Once again, it felt as if I was nuked. No, much more. The only way I could describe the explosion that occurred was ‘The Big Bang’. I gasped as I felt my body not just double in size. Not just triple. Not even quadruple. Much… much beyond that. So far beyond that, that I couldn’t even grasp the scale at which I was in size. I felt multiple rock-textured things bump into my body before cracking into dust. These would be planets. Perhaps the ones that I had watched dot the night sky all of my life. One after the other as everything surged to impossibly large standards. My arms permanently locked themselves into a 90 degree angle as my legs locked themselves as well. I very quickly transformed from nearly immobile into a beyond immobile status of muscle. Pure brawn on brawn. Even something as small as one ab on my stomach would dwarf the entire Earth more than 10 times over.

My godly pecs forced my head into a vertical position I was only forced to look up now, my traps completely blocking all hearing as they rose up past my head as well. My only circle of vision reached far above me. Even my cock at this point was incomprehensibly large. It was so thick and long that I would need a telescope to see the end. I still felt each torrent of cum tearing through my body, though. Even at this point, the pleasure was still only building higher.

All of the sudden, everything felt different. Almost as if specs of glitter were spreading across the entire mass of my god-like structure. I waited in anticipation as my body wrapped around the sky before my eyes settled on it. The Milky Way. It sat between my body and the shaft of my cock, growing smaller by the moment. In not even a minute, it had completely vanished in scale.

I knew Kyle was out here too. Every so often I would catch glimpses of his obscenity covering the starry sky. I’m 100% sure that he is enjoying this just as much as I am. My brain practically melted away as the pleasure started overriding all senses. A bloated muscle ball of unidentifiable scale. Pleasure rattling through me so heavily that as limited as I was, my hips still bucked wildly with each bit of release. I felt every spec that traveled up my egregiously large, infinitely sensitive cock. If sound could be heard in space, it would be all anything or anyone would ever hear.

The remaining visibility above me only grew smaller as each muscle continued to swell. I was in pure and undeniable bliss, as I sat there much beyond immobile. My elephantine balls drifted through the cosmos as each cascade of cum crashed through entire galaxies, only gaining more momentum and speed as I bloated up further. The milky way was now too small to compare to even an atom of my size. Each bicep was now flexed so large that it came close to rivaling my height in thickness. This same concept applied to every single muscle. Musclebound beyond musclebound. Unstoppable. A true deity above all. How large would I grow? Would it stop when I outgrow the universe? The multiverse? The omniverse? The very fabric of reality? Beyond that? Who knows. But one thing is for certain. As long as I keep feeling the pleasure, I will keep growing. I will savor every moment. Every pound. Every inch of mass. And that is perfect.
